In Stephen King's novel as well as the "It" film adaptations, Henry Bowers' menacing sociopathy is second only to Pennywise himself. As the head of the Bowers Gang, Henry and his cronies terrorize the Losers' Club. Henry, meanwhile, is subject to abuse at the hands of his father, Oscar "Butch" Bowers, an officer with the Derry Police Department. When Henry is driven insane by Pennywise, he murders Butch and lands himself in the mental hospital.
Andy Muschietti's "Welcome to Derry" update confirms that law enforcement runs in the Bowers family, though it's unclear if Clint is Henry's grandfather, great uncle, or some other relative. Also unclear is whether the Bowers' cycle of abuse is multigenerational, or whether Clint is an outlier.
There's also no word as to who is playing Clint Bowers, though some preliminary casting was announced. Taylour Paige, Jovan Adepo, James Remar, Chris Chalk, Madeleine Stowe, and Stephen Rider are set to star. Of that group, Remar fits into Clint's demographic, though it's possible the actor playing him hasn't been revealed yet. Notably, Bill Skarsgård won't return as Pennywise.
"Welcome to Derry" is slated to premiere sometime in 2024.
